Eaton 10250T330 – Frequently Asked Questions

1) Will the Eaton 10250T potentiometer fit a standard 30.5 mm panel cutout?
Yes. The 10250T heavy-duty potentiometer is built on Eaton's 30.5 mm operator form factor, so it drops into the same standard industrial panel cutout used for 30.5 mm pushbuttons and selector switches. Plan your panel layout around the device envelope of 2.25 in wide by 3.25 in long/deep by 2 in high, and leave the 3.25 in behind the panel face for the body and wiring.
2) Can I mount this Eaton potentiometer in an outdoor or washdown enclosure?
Yes. The 10250T potentiometer carries a NEMA 3, 3R, 4, 4X, 12, 13 rating, which covers outdoor rain and sleet exposure (3, 3R), hosedown and washdown (4), corrosion resistance (4X), and dust, lint and coolant in indoor industrial spaces (12, 13). The enclosure rating is only realized when the device is mounted in an enclosure of the same rating with the gasket seated properly against the panel face.
3) What resistance value do I get with each Eaton 10250T potentiometer model?
Two resistance groups are offered. Models 10250T331, 10250T333, 10250T334, 10250T335 and 10250T338 are the 50,000 ohm units. Models 10250T330 and 10250T33236 are the second group (catalogued together as T330/T33236). Order by the model number, since the resistance follows the catalog number rather than being selected separately.
4) What voltage can I run through this Eaton 30.5 mm potentiometer?
It is rated 50 Vac/dc, with 2W DC coil power. That keeps it in low-voltage control and signal duty, speed reference to a drive, setpoint adjustment, lamp dimming control. It is not a line-voltage device, so do not put 120 V control power across it.
5) Can I use this potentiometer alongside my existing 10250T pushbuttons and selector switches?
Yes, that is the point of it. It belongs to Eaton's 10250T heavy-duty operator line, so it shares the 30.5 mm mounting with the rest of the series and lines up in the same row of panel holes as the 10250T pushbuttons, selectors and pilot lights already on the door. For a plant standardizing on one operator family, this is the analog adjustment device in that family.
6) Does the Eaton 10250T potentiometer come with a knob, or do I have to buy one separately?
The knob and a large dial plate ship with the unit, so nothing extra is needed to put it on a panel and have an operator read the setting. The large dial plate is the reason this configuration gets specified for machine tool and process panels where a technician has to return to a repeatable setting.
7) What is the difference between the Eaton 10250T330 and the 10250T33236?
Both fall in the same T330/T33236 resistance group, so the electrical value is not what separates them. They are two distinct catalog numbers, 10250T330 and 10250T33236, and each carries its own manufacturer part number for ordering. If you are matching an existing device in a panel, copy the full catalog number off the old unit rather than ordering by resistance alone.
